Chronic intravascular hemolysis after aortic valve replacement. Long-term study comparing different types of ball-valve prostheses.
To assess the severity of hemolysis and to determine whether severity of hemolysis was related to type of prosthesis, hematocrit readings (Hct), schistocyte counts (S), reticulocyte counts (R), and determinations of haptoglobin (Hp), lactic acid dehydrogenase (LDH), bilirubin, urinary hemoglobin, and urinary hemosiderin (Hs) were performed on 54 patients who had three different types of aortic ...
متن کاملChronic haemolysis following insertion of ball valve prostheses.
Intravascular haemolysis after the insertion of intracardiac prosthetic material has been reported by Sayed et al. (1961), Verdon, Forrester, and Crosby (1963), Sigler et al. (1963), Gehrmann and Loogen (1964), Reed and Dunn (1964), Marsh (1964), and Yacoub, Rogers, and Taylor (1965). The haemolysis may be sufficient to produce clinical haemolytic anaemia or may cause a compensated haemolytic s...

متن کاملChronic Hemolysis Following Mitral Valve Replacement
The incidence and severity of chronic intravascular hemolysis was evaluated in a total of 41 patients following mitral valve replacement. Valve replacement was with a gamma-radiated frame-mounted aortic homograft in 21 patients and with a composite seat Starr-Edwards prosthesis, model 6310 or 6320, in 20 patients. The parameters used to assess hemolysis were hemoglobin, hematocrit, reticulocyte...
متن کاملKnowledge of patients with mechanical valve prostheses concerning chronic oral anticoagulant therapy.
Adherence to chronic Oral Anticoagulant Therapy (OAT) is directly related to patients' understanding of the therapy. This study verified the knowledge of patients with mechanical valve prostheses concerning OAT. This is a contemporary cross-sectional study, the sample is composed of patients with mechanical valve prostheses (MVP) in outpatient follow-up. A 10-question instrument was used; answe...
